Intellij IDEA (Ultimate) with Glassfish 5.0 (Local) Debugger Settings

Question

• I have a Java Web Application and a web container Glassfish 5.0 with some custom java agent attached to the container.
• I want to Debug my application as well as attach a Remote Debugger to Debug my Agent code simultaneously.
• I am using Intellij IDEA Ultimate.
• Now in the Intellij Run Configuration for Glassfish, I do the usual settings with some domain name. For Debug options "-agentlib:jdwp=transport=dt_socket,address=9100,server=y,suspend=n" I want to make 'servey=y, suspend=y' , NO COMPROMISE ON THAT.
• I try doing that by changing the 'domain.xml' but when I open my intellij glassfish configuration setting it gives me 'Warning : Debugger Settings are Invalid...' , I click Fix and the domain.xml is changed back to default with 'server=n,suspend=y'.
• I tried changing from the Glassfish Administration console as well, both the default-config and server-config, but no luck.
• WORKAROUND : I can deploy a WAR / Exploded WAR of my Application in glassfish domain folder, and customize 'domain.xml' and run the domain in debug mode ./asadmin start-domain --debug domain1, then I can successfully attach a Remote Debugger. BUT THIS ALLOWS TO ONLY DEBUG MY AGENT CODE and NOT MY APPLICATION
• I suppose this is a problem with Intellij IDEA. Does anyone have a fix for this ?
